The folding flaps 12 and 13 are continuously provided above and below the side panel 4.

  The front panel 1 has a knob portion 1a in which a tip protruding portion is formed by a U-shaped notch α applied to the top panel 6 at the center of the upper portion, and obliquely laterally from both sides of the root of the knob portion 1a. Spreading break lines a and b are provided. The left and right side panels 3 and 4 are provided with break lines c and d extending from the front ends of the break lines a and b of the front panel 1 to the back panel 2, respectively. A break line e is provided at a position overlapping the break line c of the side panel 3 during assembly. The inclination angle of the break lines a and b formed on the front panel 1 may be determined in consideration of the shape of the mountain shape remaining after the break. Usually, it is preferable to set in the range of 30 to 45 degrees with respect to the transverse direction of the front panel 1.

  The back panel 2 is provided with folded lines m that are connected to the fracture lines c and d of the left and right side panels 3 and 4 in a transverse state. In addition, the top panel 6 is formed with a slit β that extends from the center of the U-shaped cut α to the middle toward the back side.

  In the blank of FIG. 2, the front panel 1 is provided with a jumper at the U-shaped cut α that defines the knob portion 1 a, and the break lines a and b of the front panel 1 and the break lines c and In order to ensure that the breakage is performed, d is assumed to have a continuous Y-shaped cut. In addition, the folding line m of the back panel 2 is assumed to have a continuous S-shaped cut except for the vicinity of both ends in order to make it difficult to return when folded. In addition, you may make it provide a square-shaped notch from the end crossing the back panel 2 to the end.

  The pouch is housed in a paper carton formed by assembling the blank of FIG. 2 to form the food package shown in FIG. 1, but as a first step, the blank of FIG. Supply to the filling process. Specifically, the blank is folded at the boundary between the back panel 2 and the side panel 4 and the boundary between the front panel 1 and the side panel 3, and the front side of the bonding panel 5 and the back side of the side panel 3 are glued and folded.
